Answer:
Option c is the correct answer.
Step-by-step explanation:
1 -2 3 -2
6 2 2 -48
1 4 3 -38
R2-6R!=R2
R3-R1=R3
1 -2 3 -2
0 14 -16 -36
0 6 0 -36
R3/6=R3
1 -2 3 -2
0 14 -16 -36
0 1 0 -6
The last row gives y =-6
II row gives 14y-16z=-36 : Substitute for y to get z=-3
From I row x-2y+3z=-2
Substitute for y and z
x=-2+2y-3z = -5
Hence correct solution is
(-5,-6,-3)
Answer:
0.5625
Step-by-step explanation:
80-35=45
45/80 x 100%=0.5625
4x+y=-9
4(k)+3=-9
4k=-12
k=-3
Answer:
I believe your answer would be C. square root of 67
Step-by-step explanation:
If 8 is the square root of 64 and the missing number is just over 8, square root of 72 would be too much and A. and D. would be too little. I do deeply apologize if this is incorrect.
Answer:
Hello! answer: x = 29 and I don't know for sure but I think y = 61 answer that at your own risk though! Hope that helps!
